I want to move back with my mum 19 W pregnant

I know this is weird but does anyone relate at all…

I’m 22 and 19 weeks pregnant. I’ve not lived with my mum since 15 but lately I just miss her so much and wish I could move back in with her. I don’t know why.. my home situation and my partner are great we just bought our first house in a lovely area etc and I see my mum fairly regularly

I just wish I could live with her sometimes. Is it because I’m pregnant and hormonal lol
